Depositional systems and oil and gas plays in the Cretaceous Olmos Formation, South Texas
This study covers an eight-county area and includes almost the entire subsurface extent of the formation from outcrop in Maverick County to the Cretaceous shelf edge in Webb and La Salle Counties. The authors trace the development and depositional environments of the Catarina and Big Foot delta systems and the Rocky Creek barrier/strandplain system and discuss the seven oil and gas plays in the Olmos formation, including active downdip oil, gas, and condensate-rich plays along the Lower Cretaceous shelf edge in La Salle and McMullen Counties. Recent developments in Olmos trends suggest that the best years of production may lie ahead. Youthful shelf-edge gas, condensate, and oil plays are highly productive and, together with wildcat prospects further basinward, offer the best potential for continued high-level production from this mature province.
